CONSTRUCTION OF COCKS.

Application filed February 20, 1913.

To all whom it may concern.

Be it known that I, RENE BABLON, manufacturer, citizen of the FrenchRepublic, residing at 14 Rue de Bagnolet, Les Lilas, Department of theSeine, France, have invented certain new and useful Improvements in theConstruction of Cocks, of which the following is a specification.

In the known types of cooks, the different members are kept in place bymeans of screws, nuts, dowels, etc. These securing members are apt towork loose, the result being, at least, a leakage or even the loss ofone of the principal members. In certain cases, serious accidents haveresulted. Fur thermore the dismounting and assembling of these cocksrequire a rather long period of time and the use of tools which are notalways accessible.

The cock forming the object of the pres ent invention is for the purposeof prevent ing the possibility of the members working loose accidentallyand getting lost. Moreover it insures automatic compensation of the playwhich tends to arise in consequence of the wear of the spigot and thebody of the cock, all leakage being thereby prevented. However, thedismounting and assembling of these members can be eliected manually ina very short period of time and without the necessity of using any kindof tool.

The accompanying drawings represent, by way of example, three variantsof the device arranged in accordance with the principle of theinvention.

Figure 1 is a lateral elevation of a cock. Fig. 2 represents the samecock in longitudinal section. Fig. 3 is a plan. Fig. 4 is a plan view atthe moment of dismounting. Fig. 5 shows a vertical section through theaxis of the spigot. Fig. 6 is a longitudinal section through a variantof the device. Fig. 7 is a plan of said variant. Fig. 8 representspartly in elevation and partly in section, another variant moreparticularly in tended to be operated by means of cords or draw-chains.Fig. 9 is a plan of this variant. Fig. 10 is a view of the spigot andbody of the cock from below. Fig. 1 gives a view of the cock as a whole,consisting essentially of three members; a body 1, a spigot 2 fittinginto said body and a handle 3, of any shape whatsoever, intended to turnthe spigot into the opening and closing positions.

The body 1 is provided with a portion 4,

either cast in one piece with or screwed on to it, and exhibiting acircular groove 18 and a corresponding projection 8 interrupted by a gap91O as shown in Fig. 4:. Two recesses 5 are provided in the upper flangeof the groove 18. The spigot is provided with a groove 17 enabling it tobe embraced easily by the portion marked 2 in Fig. 1.

The operating handle 3 2) is provided with two lugs 6 of such dimensionsthat they can enter the recesses 5 and move inside the circular groove18. This handle is able to fit, without any play, into a slot 16 in thespigot 2, (Fig. This latter is provided with a projecting pin 11 and apassage 1-1 housing a spring 15. The passage 14 is bounded at its upperportion by the slot 16. The aggregate thus constituted operates in thefollowing manner: The spigot 2 provided with the spring 15 beinginserted into the body 1 so that the slot 16 faces the recesses 5, (Fig.t) the handle represented by broken lines is inserted in the slot 16.The lugs 6 pass through the recesses 5 and enter the circular groove 18.At this moment, the projecting pin rests on the ridge 8, (Fig. 4) andall that is needed is to turn the handle 3 toward the left in orderthat, as a result of the movement of the spigot 2 in the same direction,the said pin may drop into the gap intended for its reception. Under theaction of the spring 15, the spigot enters the body completely and,henceforward, its movement of rotation will be restricted by the pinmaking contact against 9 or 10, respectively. The handle will thereforetake up the extreme positions marked by full and broken lines in Fig. 3,according as the cock is open or shut, describing the arcs a .7), 0 d.This movement however will never bring the lugs 6 oppo site the recesses5. On the other hand, the spring 15 by bearing against the handle 3,keeps the spigot 2 embedded in the body 1 and the pin in its gap. It istherefore im possible for the aggregate to become dismountedspontaneously and, in proportion as the spigot gets worn into the body,the play is automatically corrected by the action of the spring 15.Finally, this spring being situated internally and thus protected fromall shook does not get out of order. To take the cock to pieces all thatis needed is to draw the spigot out of the body in order to disengagethe pin from its gap, then turn the handle 3 so as to bring it oppositethe recesses 5, whereupon the handle and spigot can be drawn out withease. Owing to its direction, the movement for drawing out the spigotcannot be performed except with the definite intention of taking thecock to pieces.

Figs. 6 and 7 represent a constructional variant of the cock justdescribed. It is easy to see, from an examination of Fig. 6, that thisvariant is constituted by the same members as the previous cock with thesole difference that the groove 18 is arranged internally instead of onthe outside. The recesses 5 are consequently arranged on the inside ofthe upper flange of the groove 18 and the lugs 6 of the handle pointtoward the outside instead of toward the inside. This variant has beendrawn as a cock with a body that is open underneath, an arrangementenabling the spigot to be pushed up from below when taking the cock topieces, and

I since the groove 17 is no longer needed, the

length of the spigot can be reduced.

Figs. 8, 9 and '10 show another variant based, in all cases, on the sameprinciple. The spigot of the cock is formed of a truncoconical core 2provided in its upper part with a projecting ridge 19 in which arearranged two gaps 2021, 2223 in diametrically opposite positions, whilein its lower part it is provided with two diametrically oppositesectional ridges 24: and 25 each of which occupies one fourth of thecircumference (Fig. 10)." When the spigot is in position in the body ofthe cock, its movements are limited by a projecting pin 11 carried bythe body and against which abut theends of the sectional ribs 2 1 or 25.The handle consists of a cylindrical metal rod 26 the ends of which areof smaller diameter than the central portion 27. The upper part of thebody is I pierced by two diametrically opposite grooves, one of which isvisible at 28 in Fig. v8. The widthof these grooves is equal to thediameter of the ends 26 of the handle rod. At one of their diametricallyopposite ends, each of them exhibits a circular enlargement 29 thediameter of which corresponds to that of the central enlarged portion 27of the handle rod. A spring 7 15 is housed in a cavity bored along theaxis of the spigot.

This cock is assembled in the following manner: The spigot is insertedinto the body so that the gaps 20-21 and 2223 are respectively oppositethe enlarged orifices 29. The pin 11 then bears on one of the sectionalribs 24: or 25, the spring is placed in its housing and the rod 26, 27is inserted in one of the orifices 29, passed into the gaps 2021 and 2223 and finally pushed through the orifice 29 diametrically opposite tothat through which it was inserted. During the opera-1 tion, care hasbeen taken to lower the spring 15 so that once the rod is in position itis underneath said rod and bears against same (Fig. 8.) If then thespigot be turned by pin 11 ceases to bear on one of the sectional ribs24 or 25 and the spigot takes up its place inside the body under theaction of the spring 15. From this moment, it is evident that the cockcan no longer be dismounted unintentionally, the movement of the spigotbeing restricted to 90 by the pin 11 and the projections 124. and 25which are disposed in such a manner that the rod 26 can no longer comeopposite the orifices 29 when it is moved. The rod 26 is therefore heldin place owing to the fact that its enlarged portion 27 cannot passthrough the grooves 28. To take the cock to pieces all that is needed isto press against the bottom of the spigot to cause it to rise andreleasethe pin 11,, the rod 26 being then turned to bring it opposite theorifices 29, and drawn out. 7

The cocks described above present the following advantages: The maximumsafety in use, owing to the elimination of any parts apt to causeleakage; immediate dismounti-ng without the aid .of a tool, thusfacilitating the rapid greasing and cleaning; automatic compensation ofwear. on the spigot similar members employedin the. same way,

without departing from the principle of the invention.

-What I claim is:

A cock comprising in conbination a body portion formed with a circulargroove, with the upper flange thereof presenting two diametricallyopposite notches, and an upper arcular ridge; a slotted spigot locatedin said body portion and carrying a pin primarily engaging said ridge; ahandle adapted to seat in the slot in said spigot and formed with lugsadapted to pass through said slots prior to'their engagement with saidcircular groove; and a spring located between said spigot and saidhandle and adapted upon a partial rotation of said handle and spigot toforce the spigot into a position in which said pin is located betweenthe ends of said arcular ridge.

In testimony whereof I aflix'my signatur in presence of two witnesses.
